The characteristics associated with a streamlined form, often involving a smooth, elongated profile and minimized frontal area, reduce resistance encountered when moving through a fluid medium like air or water. A classic example is the shape of a fish or a high-speed train.
Reducing drag, which is the force resisting motion through a fluid, is paramount for achieving higher speeds and improved fuel efficiency. This principle has been applied extensively in various fields, from aeronautical engineering and automotive design to the development of underwater vehicles and even architecture. Historically, the pursuit of streamlined forms revolutionized transportation, enabling faster travel and reducing energy consumption.
